Still being prompted after entering a valid input value - c++

Question

I made this for an assignment but even if I enter a valid input from the desired range I still get prompted. This is happening to both input prompts. I suspect the problem is in the while blocks of the setupGame function.
#include <iostream>
using namespace std;
bool setupGame(int numberRef, int triesRef);
int main(){
cout<<"hello world";
setupGame(4,4);
cout<<"enough";
}
//SETUP GAME FUNCTION
bool setupGame(int numberRef, int triesRef) {
do {
cout << "ENTER A NUMBER BETWEEN 1 and 100" << endl;
cin >> numberRef;
cin.clear();
//your code here
cout << "You entered: " << numberRef << endl;
if (numberRef==-1) {
cout << "You do not want to set a number " << endl;
cout << "so you stopped the program" << endl;
}
else if(numberRef >=1 && numberRef <=100)
do {
cout << "ENTER TRIES BETWEEN 3 and 7" << endl;
cin >> triesRef;
cin.clear();
//cin.ignore( '\n');
cout<< "You entered: "<< triesRef<< endl;
if (triesRef==-1) {
cout << "You do not want to set tries. ";
cout << "so you stopped the program" << endl;
} else if(triesRef <= 3 && triesRef >= 7){
cout<<"Number of tries should be between 3 and 7";
}
}
while(numberRef >=1 && numberRef <=100);{
return true;
}
}
while(triesRef >= 3 && triesRef <= 7);{
return true;
} }

You're tangling yourself up with these nested loops. Your prompt keeps printing because the while loop:
while(numberRef >=1 && numberRef <=100)
is going to keep repeating it's preceding do block until you enter a value less than 1 or greater than 100, same goes for the last while loop as well.
I assume you're using cin.clear() to flush the previous input, if you are then stop it, that is not the purpose of cin.clear(). It's instead use to clear the error state of cin. Please thoroughly read up on it here.
Below is the code to achieve what you want, please observe how I implemented the while loops after each cin prompt to ensure that a valid character is entered.
#include <iostream>
#include <fstream>
using namespace std;
bool setupGame(int numberRef, int triesRef);
int main(){
cout<<"hello world";
setupGame(4,4);
cout<<"enough";
}
//SETUP GAME FUNCTION
bool setupGame(int numberRef, int triesRef) {
cout << "ENTER A NUMBER BETWEEN 1 and 100" << endl;
cin >> numberRef;
while((numberRef < 1 || numberRef > 100 || cin.fail()) && numberRef != -1) {
cin.clear(); // Used to clear error state of cin
cin.ignore(); // Might want to ignore the whole line
cout<<"Number should be between 1 and 100, or -1 , please try again: ";
cin>>numberRef;
}
cout << "You entered: " << numberRef << endl;
if (numberRef==-1) {
cout << "You do not want to set a number " << endl;
cout << "so you stopped the program" << endl;
}
if(numberRef >=1 && numberRef <=100) {
cout << "ENTER TRIES BETWEEN 3 and 7" << endl;
cin >> triesRef;
while(triesRef < 3 || triesRef > 7 || cin.fail()) {
cin.clear(); // Used to clear error state of cin
cin.ignore(); // Might want to ignore the whole line
cout<<"Tries should be between 3 and 7 , please try again: ";
cin>>triesRef;
}
cout<< "You entered: "<< triesRef<< endl;
if (triesRef==-1) {
cout << "You do not want to set tries. ";
cout << "so you stopped the program" << endl;
return false;
}
}
}
